PLS 6 EXAM 90+ QUESTIONS &
ANSWERS |AGRADE
Floriculture - Answer- The cultivation of ornamental plants. Includes cut flowers,
bedding plants, container-grown landscape plants, flowering potted and foliage potted
plants
stamen - Answer- the male reproductive organ of a flower. Made up of anther and
filament
Anther - Answer- part of the stamen that produces pollen
Sepals - Answer- outermost circle of flower parts that encloses a bud before it opens
and protects the flower while it is developing
Carpel/Pistil - Answer- The female reproductive organ of a flower, consisting of the
stigma, style, and ovary.
stigma - Answer- the part of a pistil that receives the pollen during pollination.
ovary - Answer- A flower structure that encloses and protects ovules and seeds as they
develop. Eventually develops into fruit
Perfect - Answer- flower contains both stamens and pistils (female and male
reproductive parts)
Imperfect - Answer- individual flower is either male or female
Monoecious - Answer- imperfect flowers that appear on the same plant (both male and
female flowers on same plant)
Dioecious - Answer- imperfect flower where specimen is either male or female (Ex)
ginko trees
complete - Answer- Flower has sepals, petals, stamens and carpels/pistils
incomplete - Answer- flower lacks 1+ structure (includes all imperfect flowers)
inflorescence - Answer- A group of flowers tightly clustered together (or the
arrangement of flowers on the axis.)
Simple - Answer- one single flower/stalk
, Compound - Answer- more than one flower grouped together, and inflorescence looks
like many flowers
Composite - Answer- more than one flower grouped together and inflorescence looks
like 1 blossom/flower
Raceme - Answer- compound flower form where a long stem has short flower stalks
Spike - Answer- a compound flower form where flowers are close to stem
Corymb - Answer- compound flower form where short flower stalks branch out to create
flat top
Carl Linnaeus - Answer- Swedish botanist who developed modern scheme for
classifying plants (wrote book called Systema Natura in 1753.) Used Latin genus and
species
taxonomy - Answer- scientific work of defining groups of organisms based on physical
characteristics
kingdom, phylum, class, order, family, genus, species - Answer- Taxonomic
classification of plants
Asexual propagation - Answer- making cuttings and turning those into whole plants
tissue culture - Answer- cells/groups of cells are manipulated to grow and form new
plant tissue in vessel that is otherwise sterile
sexual propagation - Answer- uses organisms' male and female parts to grow seed
(fertilization -> seed germination when conditions are met)
Hybridization - Answer- breeders use sexual propagation to breed different varieties of a
plant type and achieve certain desired characteristics
Basic crosses - Answer- take pollen from 1 flower and place on stigma of another flower
of plant of same species
Pollen transfer - Answer- can take place naturally with wind, insects, birds, self-
pollination
Gregor Mendel - Answer- first plant breeder/geneticist
Albrecht Durer - Answer- (1471-1528) botanical artist who illustrated plants in very
detailed manner
